Condensing Pool Heater

22/12/08

Condensate Connection

The direction of the plastic condensate drain pipe

connection can be altered from the factory position

on the left, to the right.

 Remove the blanking plate from the left hand

side (See Fig. 3.1)

 Loosen the two screws holding the Trap

bracket and swivel the trap through 90 degrees.

 Secure the bracket and fit the supplied 40 mm

pipe.

 Example installations are shown in Fig 7.0.

 Fit blanking plate to the right hand side.

(See Fig 7.1)

Where possible an internal termination of the con-

densate discharge pipework should be used.

If this is not possible external pipes should be kept

as short as possible and insulated.

Where fitted in pipework that includes another trap

or a pump, for example the filter backwash pipework

to drain, an Air Break should be fitted between the

Heater and that pipework.

Avoid connecting to a kitchen sink trap as the solids

and fats in the drain will cause a blockage.

It is permissible to connect to an external gully or

rain water hopper provided they connect to a com-

bined system.

The condensate should not be run into a ‘grey water’

recycle system.

If the condensate pipe is connected to a stack it

should join not less than 450 mm above the foot of

the stack. In addition it should be positioned so there

no chance of cross-flow to another connection.

Installation pipework must be in 1¼” or 40 mm

Hunter plastic pipe to a suitable drain location with a

gradient of 2.5° (45mm/ metre run) minimum. If

connected to another drainage trap, an air break is

required between the Heater drain and that trap.

(See Fig.7.0 & 7.1). External runs, should, if possi-

ble, be insulated to defer problems from freezing.

Check during commissioning that there is a leak free

working connection from the Heater to the drain.

The simplest way to do this is to carefully pour some

water into the boiler flue and check it emerges at the

drain. This will also fill the trap ready for operation.

Procedure for Dwellings” can be refered to, see

Electrical Connections

WARNING: The appliance MUST be earthed.

All wiring for the Heater and system controls MUST

conform to I.E.E. Wiring Regulations, and work

should be tested using a suitable meter, for Earth

Continuity, Polarity, Short Circuit and Resistance to

Earth.

The Heater supply must be through a common

isolator, a double pole 3A fused isolating switch with

a contact separation of 3mm minimum on both

poles.

The cable used should be no less than 0.75mm

BS.6500 PVC, 3 core, and fixed ensuring the earth

connection is longer than the Live and Neutral.

Access to the Heater connections is made by the

removal of the Front Top Panel and the Electrical

Chassis cover, two screws.

The simplest and most flexible control scheme is to

use a Certikin CCP01 Control Unit. This provides

an electrical safety trip and timer with outputs for

the Heater, lights and an auxilary voltage free

output. It is pre-wired and tested and provided in a

standard IP55 plastic control box.

The Heater’s internal wiring is shown in Fig.11.0.

Connections are as follows :-

4 Way Terminal Supply Connection

Earth

N Mains Neutral

SL Switched Live

L Permanent Live

A factory installed link has been fitted between SL

and L which should be removed if the Heater is to

have its own switched supply.

For systems using an external programmer, the

electrical wiring should follow the relevant control

manufacturer’s recommendations, with the

switched live from the controls returning to SL in the

4 way push-fit connector.

It is possible to connect several Heaters together

using the Multiple Heater Kit. Details for the parts

and installation of this kit are given on Page 17.
